This is a voltage controlled oscillator (VCO) with great precision, designed to be stable even in the case of power supply fluctuations. Supplied with a octave selector of 10 positions from 32? to 1/16? (C0~C9).

Outputs:

Triangle

Ramp

PWM

Sine

Even (waveshape with emphasis on the even harmonics)

Inputs:

Hard sync. This forces the core to down in the event of change to zero of the input

V/oct. Two inputs for pitch control summed to the main octave selector and the tone control.
